What is the function of the phenanthroline solution that is added to the unknown iron?
phenanthroline is used as a redox indicator
Why was an acid added to the iron II ammonium solution before titration?
The acid is added to the iron II ammonium solution to prevent oxidation of iron II ions to iron III ions, which could lead to an inaccurate titration result. The acid helps maintain the iron II ions in their reduced state for the titration with the permanganate solution.
Why can iron be used to get copper from copper sulfate solution?
Iron can displace copper in a chemical reaction because it is a more reactive metal. When iron is added to a copper sulfate solution, the iron atoms will replace the copper atoms in the solution, forming iron sulfate and causing copper metal to be deposited. This process is known as a displacement reaction.
Why can iron be used to get copper from copper sulfate?
Iron is more reactive than copper, so when iron is added to copper sulfate solution, iron displaces copper in the reaction and forms iron sulfate. This process is known as a displacement reaction. This allows copper to be extracted from copper sulfate solution using iron.
What is the best indicator of iron stores in the body?
Serum ferritin levels are considered the best indicator of iron stores in the body. Ferritin is a protein that stores iron, so measuring its levels in the blood can provide valuable information about the body's iron status.
What is the function of the phenanthroline solution that is added to the unknown iron?
phenanthroline is used as a redox indicator
What is the function of the phenanthroline solution that is added to the unknown iron solution?
Phenanthroline solution is added to unknown iron solution to form a red-colored complex with iron ions. This complex is then used for colorimetric analysis to determine the concentration of iron present in the solution.
How can hydrochloric acid turn red in color?
When hydrochloric acid reacts with iron, it forms iron(III) chloride, which appears red in color. This happens because of the oxidation state change in the iron ions during the reaction, leading to the red coloration.
What happens when iron oxide is added to sodium hydroxide solution?
When iron oxide is added to sodium hydroxide solution, a reaction occurs to form iron(III) hydroxide and water. The iron(III) hydroxide will appear as a brownish precipitate in the solution, while water remains as a liquid.
Is iron is an indicator?
its an indicator
What happens when iron nail is added to zinc sulphate solution?
When an iron nail is added to zinc sulfate solution, a displacement reaction occurs where iron displaces zinc from the solution. This results in the formation of iron sulfate solution and zinc metal deposited on the iron nail. The reaction can be represented as: Fe(s) + ZnSO4(aq) -> FeSO4(aq) + Zn(s).
Why was an acid added to the iron II ammonium solution before titration?
The acid is added to the iron II ammonium solution to prevent oxidation of iron II ions to iron III ions, which could lead to an inaccurate titration result. The acid helps maintain the iron II ions in their reduced state for the titration with the permanganate solution.
What would happen if you added iron to a solution of magnesium sulphate?
If you add iron to a solution of magnesium sulfate, a displacement reaction would occur, where the iron would displace the magnesium in the sulfate compound. This would result in the formation of iron sulfate and magnesium metal.
Why can iron be used to get copper from copper sulfate solution?
Iron can displace copper in a chemical reaction because it is a more reactive metal. When iron is added to a copper sulfate solution, the iron atoms will replace the copper atoms in the solution, forming iron sulfate and causing copper metal to be deposited. This process is known as a displacement reaction.
What happens when a piece of copper is added to iron II chloride solution?
When a piece of copper is added to an iron II chloride solution, a single displacement reaction occurs where the copper displaces the iron in the compound. This results in the formation of copper II chloride and iron metal precipitate. The copper atoms give electrons to the iron II ions, causing them to become solid iron.
What is the reaction between iron and copper sulfate?
When iron is added to a solution of copper sulfate, a displacement reaction occurs where the iron displaces copper from the copper sulfate solution. This results in the formation of iron sulfate and copper metal. The iron gradually dissolves in the solution, while the copper metal precipitates out.
Why acid is added to iron ammonium solution before titration?
Acid is added to the iron ammonium solution to lower the pH and prevent the hydrolysis of iron ions, which can affect the accuracy of the titration results. Acid also helps dissolve any precipitates that may form during the titration process, ensuring a clear and accurate endpoint.
